  5. Verify that the .kext file has been removed: ls grep usbserial.kext
  6. Output should be empty.
  7. After you should remove the files stored in receipts folder: cd /private/var/db/receipts/
  8. Find the enties: ls grep usbserial*
  9. Output should be: codebender.cc.ch34xinstaller.usbserial.pkg.bom codebender.cc.ch34xinstaller.usbserial.pkg.plist
